Benefits of technology
This patent describes a method and apparatus for attaching load-bearing components to an aircraft's stringer. The apparatus includes a structure that conforms to the stringer's shape and is held in place by pins that engage with the stringer's holes. The structure also has members that connect to other parts of the aircraft. The method involves placing the structure over the stringer and applying a load to it using the pins. The technical effect of this patent is to provide a reliable and secure way to attach load-bearing components to an aircraft's stringer.
Problems solved by technology
A blind fastener does not allow an operator to inspect the quality of the connection to the stringer.
A blind fastener is difficult to remove in these structures.
As a result, repositioning of the fixture may be more difficult and time consuming than desired.
As a result, the manufacturing and assembly of the aircraft may take more time and expense than desired to obtain a desired positioning of parts near the stringer.

Embodiment Construction
[0028]Referring more particularly to the drawings, embodiments of the disclosure may be described in the context of aircraft manufacturing and service method 100 as shown in FIG. 1 and aircraft 200 as shown in FIG. 2. Turning first to FIG. 1, an illustration of an aircraft manufacturing and service method is depicted in accordance with an advantageous embodiment. During pre-production, aircraft manufacturing and service method 100 may include specification and design 102 of aircraft 200 in FIG. 2 and material procurement 104.
[0029]During production, component and subassembly manufacturing 106 and system integration 108 of aircraft 200 in FIG. 2 takes place. Thereafter, aircraft 200 in FIG. 2 may go through certification and delivery 110 in order to be placed in service 112. While in service 112 by a customer, aircraft 200 in FIG. 2 is scheduled for routine maintenance and service 114, which may include modification, reconfiguration, refurbishment, and other maintenance or service.

Abstract
In one advantageous embodiment of the present disclosure, an apparatus and method for supporting a load is provided. The apparatus comprises a structure having an inner surface with a shape configured to substantially conform to an outer surface of a stringer. A number of pins extends from the inner surface of the structure such that the number of pins are configured to engage holes in the outer surface of the stringer when the structure is placed over the outer surface of the stringer. The pins support the structure with respect to the stringer when a load is applied to the structure. A number of members extends from the outer surface of the structure such that the number of members is configured to connect to a part.
Description
BACKGROUND INFORMATION[0001]1. Field[0002]The present disclosure relates to attaching structures to each other and, more particularly, to attaching aircraft structures to each other. Still more particularly, the present disclosure relates to a method and apparatus for connecting parts to an aircraft stringer.[0003]2. Background[0004]Manufacturing and assembly of structures, such as those for aircraft, involves the assembly of different parts to form the structures. Different parts and / or structures are connected to each other in manufacturing the aircraft. Structures, such as reinforcing ribs, stringers, and / or other suitable structures may be used to support other parts and / or structures in the aircraft. For example, wiring bundles, hoses, cables, and other lines are examples of parts that may run through parts of an aircraft. These lines may be connected to structures, such as ribs and / or stringers in the aircraft. These structures may be used to provide support for system compone...
